Most of the time, the shoebox-sized robot - which is being developed for the US military - uses its four wheels to get around.

But the Precision Urban Hopper can use a piston-actuated "leg" to launch it over obstacles such as walls or fences.

The semi-autonomous, GPS-guided gadget could be used for surveillance in urban environments.

The robot is allegedly able to clear obstacles up to 25-feet high. Which is exactly why I built a 26-foot fence around my anti-robot compound. And dug a moat. Which, FYI, is filled with deadly water dragons. But not luck dragons -- Falcor doesn't like to get wet! But he does like to get high. You're so soft, Falcor. Plus you have a puppy face.
